While comparing Color change garnet and Howlite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Color change garnet and Howlite chemical formula.
Another important criteria for qualitative analysis of gemstones is Color change garnet and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Color change garnet and Howlite Optical Properties during the identification of gemstone. Specific gravity of Color change garnet is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
